Reasons for dark armpits

Believe it or not, but the armpits are one of the most sensitive parts of the skin in the whole body, which explains why shaving them is inappropriate, since it'll eventually cause irritation and discomfort in this area.

A common alternative to remove armpit hair is with a razor, which eventually produces an unsightly shadow in the area, even when you've recently just shaved.

Baking soda and lemon

This condition can make you feel embarrassed to wear clothes that expose the area, because it appears that you didn't shave properly. However, there's a simple homemade solution, using baking soda to whiten the armpits and thus improving their appearance.

This ingredient, along with another equally powerful one, is to use lemon, helping you to get the best results. Baking soda and lemon can also help you whiten your teeth, discover how to use them.

The method: Use baking soda and lemon

Using baking soda to lighten the armpits is a very simple and effective process. To make it, follow the instructions.


  • 10 grams of baking soda
  • The juice of half a lemon


  1. Mix both ingredients into a thick paste.
  2. Thoroughly clean your armpits with soap and water to remove any traces of deodorant
  3. Then dry them and apply the paste evenly to both armpits.
  4. Leave on for 10 minutes and then remove with warm water and mild soap.

It's recommended to repeat the process every day for at least two weeks or until the skin has lightened.

Use a scrub

Besides using baking soda, it's recommended that you exfoliate the underarm area once or twice a week in order to remove dead skin cells that accumulate in the area, improving skin tone and appearance. It's important that you do this with a facial scrub with a fine grain that'll be much gentler on your skin, and exfoliate it without causing irritation. Using a pumice stone can also help get rid of dark underarms, though it should be used with care so your armpits don't irritate.
